G20, BRICS, and the UN are all holding summits back-to-back.

World leaders face a slew of multilateral summits over the coming month, including the BRICS meeting in South Africa, the G20 in India, and the UN General Assembly in New York. This rare convergence of top-tier international gatherings is a symptom of the increasing importance of high-level summitry in international diplomacy.

BRICS, an organization with China, Russia, India, South Africa, and Brazil, is considering expansion.

The divisive debate within BRICS over whether and how aggressively to expand membership is a sign the group lacks a clear mission and direction. But it also underscores the differences in how BRICS’ members view both the benefits they receive from the grouping and their future role in the international community.
